Abstract

The invention is directed to use of polythiophenes in a method to determine the genuineness of an article which method comprises providing an article treated with a composition comprised of a polythiophene, the polythiphene having a low temperature color and a weak fluorescence and the structure of the polythiophene being designed such that when the composition is placed in a heat-exchange relationship with the article, the low temperature color will change to a high temperature color and the weak fluorescence will change to a strong fluorescence when a pre-determined temperature is met or exceeded in the article, heating the article to a temperature that meets or exceeds the pre-determined temperature and detecting the color and the fluorescence change.
